Changes of the oceanic CO 2 sink in the Eastern Indian sector of the Southern Ocean
International audience Changes in the carbon dioxide fugacity ( f CO 2 ) and air-sea CO 2 flux observed in the Southern Ocean, south of Tasmania were analysed and compared for two different years: 1996/1997 and 2002/2003. The CO 2 flux showed large and contrasting interannual changes in the permanen...
